We're getting a course in the mechanics of bridge buillding in the Guestroom today...

Next time you're headed along Palmer River in the Centre, around the West Alligator in Kakadu, the Victoria Highway or travelled on the Berrimah overpass on Tiger Brennan Drive...make sure you check out all of these bridges....

You're about to meet the woman who built and designed them, or certainly played a primary role in their creation.

Louise McCormick is one of just two bridge engineers in the Northern Territory. Her interest in engineering and how things work started pondering the 100 year old bridge in her home town of Goondiwindi, and she's gone on to be a high achiever in the field.

She's even put her mind to that much dreamed bridge from Darwin to Mandorah...
